These nanoshells involve a quasiparticle called a plasmon which is a collective excitation or quantum plasma oscillation where the electrons simultaneously oscillate with respect to all the ions. The simultaneous oscillation can be called plasmon hybridization where the tunability of the oscillation is associated with mixture of the inner and ...
Halas' work in the 21st century focuses on noble metal nanoshells covering semiconducting or insulating cores. Her research was the first to experimentally show that nanoshells with different dimensions and shapes have different plasmonic resonances, and that these resonances could therefore be tuned by changing nanoparticle geometries.

If large concentrations quickly clear the blood vessels, the nanoshells may accumulate in major organs (mainly the liver and spleen). Residual concentrations of these particles were also found in kidneys, lungs, muscle, brain, and bone of mice after 28 days. The concentration of the solution injected intravenously 2.4*10 11 nanoshells/mL.
Gold nanoshells, coated silica nanoparticles with a thin layer of gold. [6] have been conjugated to antibodies (anti-HER2 or anti-IgG) via PEG linkers. After incubation of SKBr3 cancer cells with the gold nanoshells, an 820 nm laser was used to irradiate the cells. Only the cells incubated with the gold nanoshells conjugated with the specific ...

Naomi Halas, American biochemist focusing on nanoshells and nanophotonics; John Burdon Sanderson Haldane (1892–1962), British and Indian biochemist, geneticist and evolutionary biologist; John Scott Haldane (1860–1936), British biochemist; Charles Martin Hall (1863–1914), American chemist, famous for Hall-Héroult process
Lipid-based carriers include both liposomes and micelles. Examples of gold nanoparticles are gold nanoshells and nanocages. [3] Different types of nanomaterial being used in nanocarriers allows for hydrophobic and hydrophilic drugs to be delivered throughout the body. [5]
He has served as executive director of the Institute for Research in Lasers, Photonics and Biophotonics. Prasad has contributed to the development of photonic materials for biomedical applications including nanoshells containing various diagnostic and therapeutic agents [5] [2] He has published a book entitled "Nanophotonics,"."
